Abstract (en)
The present disclosure discloses a method and device for transcoding a video, which belongs to the video processing technology. The method includes: acquiring a target frame image of a video to be transcoded, and generating a global feature map of the target frame image based on a feature extraction module of a semantic segmentation model (101); performing feature segmentation on the global feature map based on a feature segmentation module of the semantic segmentation model, and determining a multi-level ROI of the target frame image (102); and using different transcoding rates to transcode the multi-level ROI and other regions of the target frame image respectively (103).
